"What is unique here is technology that reaches the highest level of
security while still running more software than any other IT system in the
world," commented Dan O'Dowd, founder and chief executive officer of Green
Hills Software. "Intel® Virtualization Technology accelerates guest
operating system execution performance and robustness, making this platform
even more compelling for next-generation military, intelligence, critical
infrastructure, and financial applications."

INTEGRITY Workstation incorporates a high-assurance Human Interface Device
Manager, which manages the display of information at multiple security
levels yet still supports a rich graphical environment. The Human Interface
Device Manager provides a cross-domain information transfer capability that
can be customized to support application or system-specific regrading
policies. It also provides a trusted path for the shared keyboard and mouse
devices and a multi-factor login and authentication mechanism that cannot
be spoofed.

The Leader in Safe and Secure Operating System Technology

Designed and developed to meet the most stringent security requirement --
Evaluated Assurance Level (EAL) 7 of the Common Criteria -- Green Hills
Software's INTEGRITY is the only commercially developed operating system to
be certified by in-house experts as a part of Integrated Modular Avionics
(IMA) systems by the US Federal Aviation Administration (FAA) to the
stringent DO-178B Level A, the highest level of safety in which a system
failure may be catastrophic. INTEGRITY is also the first operating system
to undergo a Common Criteria security evaluation at EAL 6+, a level of
assurance that has never been achieved by any other operating system
(http://www.ghs.com/news/20050829_eal6_skpp.html).

The Universal Operating System

INTEGRITY's flexible architecture enables it to scale from small footprint
embedded devices all the way up to enterprise class servers. INTEGRITY
Workstation is also the first operating system environment to be certified
conformant to the latest POSIX standard, POSIX.1-2003
(http://get.posixcertified.ieee.org), making it an ideal platform for the
development and deployment of open standards-based applications.

About Padded Cell Technology

INTEGRITY Workstation incorporates Green Hills Software's award-winning
Padded Cell software which enables multiple legacy operating systems and
applications to be run in secure partitions on the same computer. Unlike
other virtual machine technologies, Padded Cell never runs a single line of
virtual machine or guest operating system code in the supervisor mode of
the microprocessor, ensuring that secure applications cannot be subverted
or denied service, even if other parts of the system are connected to the
Internet and subjected to its associated hackers and worms. The resulting
platform enables systems designers to build the most security-critical
applications and run them alongside familiar operating environments, saving
cost, space, size, weight, and power over multiple hardware platforms.
